The p-Cockcroft Property of the Semi-Direct Products of Monoids

نویسنده

  • A. Sinan Çevik
چکیده

The semi-direct product of arbitrary two monoids and a presentation for this product have received considerable attention, see for instance [12], [14] and [15]. In [15], Wang defined a trivialiser set of the Squier complex associated with this presentation. In this paper, as a main result, we discuss necessary and sufficient conditions for the standard presentation of the semi-direct product of any two monoids to be p-Cockcroft for any prime p or 0. Finally we present some applications of this main theorem. 2000 Mathematics subject classification: 20M05, 20M50, 20M15, 20M99, 20L05.

On Regularity of Acts

In this article we give a characterization of monoids for which torsion freeness, ((principal) weak, strong) flatness, equalizer flatness or Condition (E) of finitely generated and (mono) cyclic acts and Condition (P) of finitely generated and cyclic acts implies regularity. A characterization of monoids for which all (finitely generated, (mono) cyclic acts are regular will be given too. We als...

Fp 1 Is Undecidable for Nitely Presented Monoids with Word Problems Decidable in Polynomial Time

In the rst part of this paper properties P of nitely presented monoids are considered that satisfy the following two conditions: (1) each monoid that can be presented through a nite convergent string-rewriting system has property P , and (2) each nitely presented monoid having property P is of homology type FP3. Following an idea presented in (Otto and Sattler-Klein 1997) it is shown that these...

On the U-WPF Acts over Monoids

Valdis Laan in [5] introduced an extension of strong flatness which is called weak pullback flatness. In this paper we introduce a new property of acts over monoids, called U-WPF which is an extension of weak pullback flatness and give a classification of monoids by this property of their acts and also a classification of monoids when this property of acts implies others. We also show that regu...

On Properties of Monoids That Are Modular for Free Products and for Certain Free Products with Amalgamated Submonoids

A property P of string-rewriting systems is called modular if the disjoint union R 1 R 2 of two string-rewriting systems R 1 and R 2 has this property if and only if R 1 and R 2 both have this property. Analogously, a property P of monoids is modular if the free product M 1 M 2 of two monoids M 1 and M 2 has this property if and only if M 1 and M 2 both have this property. Since the string-rewr...

On Condition (G-PWP)

Laan in (Ph.D Thesis, Tartu. 1999) introduced the principal weak form of Condition $(P)$ as Condition $(PWP)$ and gave some characterization of monoids by this condition of their acts. In this paper first we introduce Condition (G-PWP), a generalization of Condition $(PWP)$ of acts over monoids and then will give a characterization of monoids when all right acts satisfy this condition. We also ...
